9.6 Configuring URL Filters
Keyword based URL (Uniform Resource Locator, e.g. www.yahoo.com ) filtering allows you to define one or
more keywords that should not appear in URL’s. Any URL containing one or more of these keywords will be
blocked. This is a policy independent feature i.e. it cannot be associated to ACL rules. This feature can be
independently enabled/disabled, but works only if firewall is enabled.

setting will be ignored. Note that you must disable and then enable the firewall for this change
